(Galenos Publ House, 2024) Edis, Ebru Cakir; Cilli, Aykut; Kizilirmak, Deniz; Coskun, Ayson Sakar; Guler, Nurcan; Cicek, Sedat; Sayiner, Abdullah
Background: Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry -based studies and drug research. Aims: We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in T & uuml;rkiye to those of other countries. Study Design: A multicenter prospective cohort study. Methods: The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in T & uuml;rkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non -cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results: Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 +/- 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation -related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion: This is the first multicenter study of bronchiectasis in T & uuml;rkiye. The study results will provide important data that can guide the development of health policies in T & uuml;rkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.

Clinical features of generalized lipodystrophy in Turkey: a cohort analysis
(Wiley Online Library, 2023) Özbek, Mehmet Nuri; Yildirim Simsir, Ilgin; Tuysuz, Beyhan; Tanrikulu, Seher; Celik Guler, Merve; Akinci, Baris
Aim: To describe the Turkish generalized lipodystrophy (GL) cohort with the frequency of each complication and the death rate during the period of the follow-up. Methods: This study reports on 72 patients with GL (47 families) registered at different centres in Turkey that cover all regions of the country. The mean ± SD follow-up was 86 ± 78 months. Results: The Kaplan-Meier estimate of the median time to diagnosis of diabetes and/or prediabetes was 16 years. Hyperglycaemia was not controlled in 37 of 45 patients (82.2%) with diabetes. Hypertriglyceridaemia developed in 65 patients (90.3%). The Kaplan-Meier estimate of the median time to diagnosis of hypertriglyceridaemia was 14 years. Hypertriglyceridaemia was severe (≥ 500 mg/dl) in 38 patients (52.8%). Seven (9.7%) patients suffered from pancreatitis. The Kaplan-Meier estimate of the median time to diagnosis of hepatic steatosis was 15 years. Liver disease progressed to cirrhosis in nine patients (12.5%). Liver disease was more severe in congenital lipodystrophy type 2 (CGL2). Proteinuric chronic kidney disease (CKD) developed in 32 patients (44.4%) and cardiac disease in 23 patients (31.9%). Kaplan-Meier estimates of the median time to diagnosis of CKD and cardiac disease were 25 and 45 years, respectively. Females appeared to have a more severe metabolic disease, with an earlier onset of metabolic abnormalities. Ten patients died during the follow-up period. Causes of death were end-stage renal disease, sepsis (because of recurrent intestinal perforations, coronavirus disease, diabetic foot infection and following coronary artery bypass graft surgery), myocardial infarction, heart failure because of dilated cardiomyopathy, stroke, liver complications and angiosarcoma. Conclusions: Standard treatment approaches have only a limited impact and do not prevent the development of severe metabolic abnormalities and early onset of organ complications in GL.

Comparison of Growth Factor Levels in Injectable Platelet-Rich Fibrin Obtained From Healthy Individuals and Patients With Chronic Periodontitis: a Pilot Study
(BMC, 2024) Savas, Hasan Basri; Karci, Bilge
Background This study aimed to assess and compare the concentrations of growth factors, white blood cells (WBCs), and platelets in injectable platelet-rich fibrin (i-PRF) derived from people with healthy periodontal conditions and those with chronic periodontitis.Methods Venous blood samples were obtained from 30 patients diagnosed with chronic periodontitis (test group) and 30 participants with healthy periodontal conditions (control group). The i-PRF was then acquired from centrifuged blood. The growth factors (VEGF, IGF-1, TGF-beta 1, PDGF-BB and EGF) released from the i-PRF samples were compared between groups with ELISA testing. The amounts of WBCs and platelets were also compared.Results No significant differences in the concentrations of growth factors were found between the groups (the mean values for the control and test groups were, respectively: IGF: 38.82, 42.46; PDGF: 414.25, 466.28; VEGF: 375.69, 412.18; TGF-beta 1: 21.50, 26.21; EGF: 138.62, 154.82). The test group exhibited a significantly higher WBC count than the control group (8.80 vs. 6.60, respectively). However, the platelet count did not show a statistically significant difference between the groups (control group 242.0 vs. test group 262.50). No significant correlation was observed between WBC count and growth factor level in either group.Conclusions The growth factor levels in i-PRFs did not exhibit significant difference between the two groups. This suggests that the levels of these growth factors may be unaffected by the periodontal disease.

Early puberty paradox: an investigation of anxiety levels of mothers and children, children's quality of life, and psychiatric diagnoses
(SpringerLink, 2023) Kardaş, Burcu; Kardaş, Ömer; Demiral, Meliha; Özbek, Mehmet Nuri
Early puberty signs lead to an increase in anxiety levels of parents and children. The aim of this study was to investigate the quality of life and anxiety levels of girls and their mothers who were admitted to a pediatric endocrinology clinic with concerns about early puberty. Girls and their mothers who were admitted to endocrinology outpatient clinic with concerns about early puberty were compared to healthy control group. Screen for Child Anxiety Related Emotional Disorders (SCARED) parent form, Quality of Life for Children Scale (PedsQL) parent form, and Beck Anxiety Inventory (BAI) were administered to the mothers. Children were evaluated with the Schedule for Afective Disorders and Schizophrenia for School-Age Children (Kiddie-SADS Lifetime Version) (K-SADS-PL). The study sample consisted of 92 girls and 62 of them were administered to clinic with concerns about early puberty. There were 30 girls in early puberty group (group 1), 32 girls were in the normal development group (group 2), and 30 were in the healthy control group (group 3). The anxiety level of group 1 and group 2 was signifcantly higher, and their quality of life was signifcantly lower when compared to group 3 (p<0.001). Mother’s anxiety level was found signifcantly higher in group 2 (p<0.001). It has shown that anxiety level and quality of life of children were associated with anxiety level of mothers and the current Tanner stage (r=0.302, p<0.005). Conclusion: Mothers and children who have concerns about early puberty are negatively afected when early puberty is a possibility. For this reason, educating parents will prevent negative impacts of this situation on children. At the same time, it will decrease health burden.

Hydrogel burn dressing effectiveness in burn pain
(Elsevier Sci Ltd, 2024) Celik, Enes; Akelma, Hakan
Severe burns are painful and dramatic injuries. Studies show that pain is underestimated and often not adequately treated. This study aims to evaluate the analgesic efficacy of hydrogel burn dressing and silver sulfadiazine, which are two agents commonly used in first-aid dressings for burn patients. This study, designed as a prospective, observational, and cross-sectional study. Study included 64 pediatric patients admitted to our burn center between 01.03.2020 and 01.09.2020 who were examined by our burn service after their first treatment in the emergency dressing room. Two groups of patients were included in the study. Pain level was assessed in the dressing room before and 10 min after the procedure using the Visual Analog Scale and FLACC (Face, Legs, Activity, Cry, Consolability) pain assessment scales.During the study period, Burnaid (R) was applied to 62.5% of patients (40 patients) and silver sulfadiazine to 37.5% (24 patients). In terms of pain scores, pre-dressing FLACC values were higher in Group B (p = 0.039); post-dressing VAS and FLACC values were significantly lower in group B (p 0.001; p 0.001). In terms of additional analgesia, we found more patients in Group S received analgesics (p 0.001).We believe that its effect on burn wound pain is superior to that of silver sulfadiazine.(c) 2023 Elsevier Ltd and ISBI.

(Elsevier, 2023) Gökşen, Damla; Evin, Ferda; Işık, Esra; Özen, Samim; Atık, Tahir; Özkınay, Ferda; Akcan, Neşe; Özkan, Behzat; Büyükinan, Muammer; Özbek, Mehmet Nuri; Darcan, Şükran; Onay, Hüseyin
Aim: We aimed to investigate molecular genetic basis of monogenic diabetes (DM) and novel responsible candidate genes with targeted Next Generation Sequencing (NGS) and Whole Exome Sequencing (WES). Methods: A hundred cases presenting with clinical findings and a family history of monogenic DM were included in the study. Molecular analysis was performed using an NGS panel including 14 genes. Following targeted NGS, WES was planned in cases in whom no variant was detected. Results: Thirty different disease-causing variants in seven different genes were detected in thirty-five (35%) cases with targeted NGS approach. Most common pathogenic variant was found in GCK gene in 25 (25%) cases. Four different variants were detected in 4 (4%) patients in ABCC8 gene. In 45 of 65 cases; WES analyses were done. A heterozygous c.2635C>T(p.Gln879Ter) variant was detected in IFIH1 gene in a patient with incidental hyperglycemia. In the segregation analysis affected mother was shown to be heterozygous for the same variant. Conclusion: Molecular etiology was determined in 35% cases with the NGS targeted panel. Seventeen novel variants in monogenic DM genes have been identified. A candidate gene determined by WES analysis in a case that could not be diagnosed with NGS panel in this study.

Prevalence of obesity in elementary schools in mardin, South-Eastern of Turkey: A preliminary study
(2012) Battaloğlu İnanç, Betül; Şahin Say, Deniz; Oğuzöncül, Ayşe Ferdane; Bindak, Recep; Mungan, Feride
Amaç: Bu araştırmada, Mardin ilindeki ilköğretim çağı çocukları arasında obezite sıklığı, obezite ile aile ve çevre faktörleri arasındaki ilişki değerlendirildi. Materyal ve Metot: Çalışmada Mardin il merkezindeki, üç ilköğretim okulunda 6-15 yaş grubundaki, 3460 çocuğun boy ve ağırlık ölçümleri yapıldı. Beslenme alışkanlıkları ve aile-çevre faktörlerine ait bilgiler anket yolu ile elde edildi. Her öğrenci için vücut kitle indeksi (BMI) hesaplandı. Dünya Sağlık Örgütü (WHO) tarafından çocuk ve adolesanlarda fazla kilolu olma ve obezitenin sınıflandırılmasında kullanılması önerilen ve 2007 yılında yayınlanan 5-19 yaş grubu çocuklar ve adolesanlar için büyüme referans değerleri baz alınarak hesaplandı. Söz konusu referans değerlerine göre vücut kitle indeksi (BMI)değeri 97. persentil üzerinde olan çocuklar obez; BMI değeri 85-97. persentil arasında olanlarda fazla kilolu olarak tanımlandı. Veriler bilgisayarda SPSS istatistik programı ile değerlendirildi. Analizler için ki-kare ve t-testleri kullanıldı. P<0.05 istatistiksel olarak anlamlı kabul edildi. Bulgular: Öğrencilerin % 48.2’si kız idi. Fazla ağırlığı (overweight) olan çocuk %15.78, obez olan çocuk oranı %10.57 idi. Cinsiyete göre obezite sıklığı kız çocuklar için %9.05 ve erkek çocuklar için %11.97 idi. Erkeklerde obezite sıklığı anlamlı derecede daha yüksekti (p<0.01). 13 -15 yaş grubundaki kızların BMI ortalamaları, aynı yaş grubundaki erkeklere göre anlamlı derecede yüksekti. Sosyoekonomik düzeyi yüksek olanlarda (p<0.01), düzensiz öğün yiyenlerde (p=0.05) , günde 2 saatten fazla TV seyredenlerde (p=0.03), 6 aydan az anne sütü alanlarda (p<0,05), annesi (p<0.05) veya babası (p<0.01) obez olanlarda obezite sıklığı anlamlı derecede daha yüksek bulundu. Sonuç: Obezite bir sağlık sorunu olarak dünya çapında artmaktadır. Çocukluk çağında obez olmak ve obez ebeveyn/(ebeveynlere) sahip olmak, erişkinlikte obez olmanın risk faktörlerinden ikisidir. Yetişkinlikte, obezitenin kalıcılığı, sorunun en ciddi yönüdür. Obezitede tedavi başarı oranı, ne yazık ki yüksek değildir. Bu nedenle, rutin çocukluk çağı büyüme değerlendirilmesi için, vücut kitle indeksinin eklenerek, risk altında olanların erken tespiti ile ilgili bir önleyici strateji en akılcı yol olarak görünmektedir.

(Elsevier, 2023) Karahan, Selim; Ersoy, Ezgi; Süvari, Goncagül; Ercan, Selami; Özkan, Esra Eroğlu; Tuncay, Evin Aygün; Cantürk, Yeter Yeşil; Mataracı Kara, Emel; Zengin, Gökhan; Boğa, Mehmet
Ethnopharmacological relevance: Since ancient times, Teucrium L. species have been among the most commonly used traditional medicinal plants mainly in the Mediterranean region. From tackling gastrointestinal problems to maintaining the healthy functioning of endocrine glands, and from treating malaria to severe dermatological disorders, Teucrium species are known to have extensive therapeutic applications. Teucrium polium L. and Teucrium parviflorum Schreb. are the two members of the genus that have been used in Turkish folk medicine for various medicinal purposes. Aim of the study: To determine the phytochemical compositions of the essential oils and ethanol extracts of Teucrium polium and Teucrium parviflorum collected from different locations in Turkiye along with the investigation of in vitro antioxidant, anticancer, antimicrobial activities, and both in vitro and in silico enzyme inhibitory activities of the extracts. Materials and methods: Ethanol extracts of Teucrium polium aerial parts and roots, and aerial parts of Teucrium parviflorum were prepared. Volatile profiling of the essential oils by GC-MS, phytochemical profiling of the ethanol extracts by LC-HRMS, antioxidant activity by DPPH radical scavenging, ABTS cation radical scavenging, CUPRAC, and metal chelating activity assays, anticholinesterase, antityrosinase, antiurease, activities by different enzyme inhibitory activity assays, anticancer activity by SRB cell viability assay, and antimicrobial activity against a standard panel of bacteria and fungi by the microbroth dilution technique. Molecular docking studies were performed by Autodock Vina (Ver. 1.1.2). Results: The studied extracts were found to be quite rich in various biologically important volatile and phenolic compounds. (-)-Epigallocatechin gallate, which is a molecule renowned for having great therapeutic potential, was the major compound of all extracts. Teucrium polium aerial parts extract was revealed as a great source for naringenin with 16327 ± 685.23 μg/g extract. All extracts exerted significant antioxidant activity by different methods. All extracts demonstrated antibutrylcholinesterase, antityrosinase, and antiurease activities by in vitro and in silico assays. Teucrium polium roots extract stood out with remarkable tyrosinase and urease inhibitory and cytotoxic activities. Conclusion: The obtained results from this multi-disciplinary study proves that the traditional use of these two Teucrium species is justified, and the mechanisms behind are enlightened.
